Why Choose the Unitronics UMI-S0030 EMC Input Filter?
The Unitronics UMI-S0030 is a compact EMC C3 input filter designed to reduce electromagnetic interference generated by small variable frequency drives in industrial automation systems. Installed between the mains supply and the inverter, the filter suppresses conducted electrical noise and helps systems comply with IEC / EN 61800-3 electromagnetic compatibility requirements.
This filter is intended for single-phase 200-240 V AC installations and supports Unitronics inverter drives with power ratings from approximately 0.4 kW to 2.2 kW (0.5–3 HP). It is commonly used with Unitronics B1-series drives in small industrial machines, HVAC systems and light automation equipment.
By suppressing switching noise at the input stage of the inverter, the UMI-S0030 protects nearby electronics such as PLCs, sensors and communication equipment from interference while improving the stability of industrial control systems.
